The present invention is directed to, and it is an object to provide, a novel accumulator for coin controlled, automatic vending machines.

The accumulator is a device which translates the total value of coins, regardless of the numas said member, and the mechanical movement being part-circle relation of said shaft.

A further object of the invention is to provide an accumulator, as in the preceding paragraph, in which said mechanism is adapted to be electrically actuated; the action being rapid, yet smooth and positive, and there being automatic reset means embodied in the device.

An additional object of the invention is to provide an accumulator whose structure is rugged, reliable, and fool-proof; the device also being efiicient and accurate with respect to the translation of total coin value to an accumulated mechanical movement.

It is also an object of the invention to provide a practical and relatively simple accumulator, and one which will be exceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings:

Fig. l is a plan view of the accumulator with the parts in starting position.

Fig. 2 is a fragmentary side elevation, with a bank of the holding pins in advanced or out of the way position to permit corresponding rota- I tion of the control disc and mounting shaft.

Fig. 3 is a transverse section on line 3-3 of Fig. 1.

I coin boxes and accumulator actuating solenoids.

Referring now more particularly to the charactors of reference on the drawings, the device 6 Claims. (Cl. 1941) comprises a rectangular upstanding housing, indicatedgenerally at I, supported by a base 2, and said housing includes spaced vertical walls 3 and 4.

Outwardly of the wall 3 there is a vertical mounting plate 5 supported in facing parallel relation to said wall 3, by bolts 6 and spacers I. Some distance above the base 2, the housing is fitted with a horizontal shaft 8 which extends in journaled relation from the wall 4, and through the wall 3 and mounting plate 5.

Between the wall 3 and plate 5 the shaft 8 is fitted with a control disc 9 of substantial diameter; such control disc 9 being formed as a pulley at its periphery and is adapted to be driven by an endless belt and pulley unit In from an electric motor I I mounted in the lower portion of the housing I. The endless belt and pulley unit It includes a relatively small drive pulley I2 on the motor shaft. The direction of rotation of the control disc 9 is indicated by the arrow in Fig. 3.

The control disc 9 is fitted, in its peripheral portion, with a continuous or circumferential row of transversely slidable pins I3; such pins I3 being of a length greater than the thickness of said control disc 9 whereby said pins may be shifted axially from one side or the other of the disc in the manner hereinafter described.

The pins in the upper portion of the row thereof project inwardly from the disc 9 a certain extent, but terminate short of the wall 3. This is their retracted position. Between said upper portion of the row of pins I3 and the wall 3 there is an arcuate presser head assembly, indicated generally at I4; such presser head assembly including a plurality of arcuate presser heads I5, IE, IT, and I8 of progressively greater arcuate extent, respectively. The presser heads I5-I8 inclusive are normally retracted into engagement with the wall 3, thus being ineffective with respect to the adjacent or corresponding upper portion of the row of pins l3; such presser heads being mounted on push rods I9, 20, 2|, and 22, respectively. The push rods I9-22 inclusive are slidably supported in connection with, and extend between, the walls 3 and 4, projecting outwardly of the latter and there being fitted with heads 23.

It will be noted that upon advance of any one of the push rods I 9-22 inclusive, a corresponding one of the presser heads I5-I8 inclusive will be advanced, for the purpose hereinafter described.

The push red I 9 is fitted, intermediate its ends, with a stop 24, and a loaded compression spring 25 surrounds said push rod between the stop 24 and the wall 3 to normally maintain said rod retracted, as in Fig. l.

The push rod 293 includes a laterally projectin stop 25 cooperating with the back side of the stop 24; the push rod 2! including a laterally projecting stop 2? cooperating with the back side of the stop 26; and-the pushrod 22iincludingialaterally projecting stop 28 which cooperates with the back side of the stop 21.

With this arrangement advance of the rod is has no effect on the other rods; advance of the rod 29 advances also the rod I9; advance of the rod 2| advances also the rods'fZ[hand-.115; .andadadvance of the rod 22 advances also..the rods .2], 20, and l 9.

The rods iii-22 inclusive ,are adapted to be power advanced by corresponding solenoids 29, 3t, 3!, and 32, indicated diagrammatically in Fig. 5, and adapted to ;be mounted exteriorly of he hou ing 1 ,in. a manner-suchthat thesolenoid rl ne rs- 3 are axially alinedin actuating .relainclusive are for-one cent, fivecents, ten cents,

and twenty-five .cents,,respectively; the present embodiment of :the accumulator being for the control of the dispensing of an article whose price is twenty-five cents (or twenty-six cents,

including one cent sales tax) .The wall ,3 isfiitted with-an upwardly facing stop 39 which is normallyiengaged by the lead one of the retracted pinsil3 in the upperportion of :the circumferential row thereof. The armate :presser. head assembly l 4 extendsin matching relation to saidupper portion of the circum ferential row of pins l3 backward from said lead one thereof. The presser heads 15,16, l7, and

i8 are of an arcuate extent to engage one, four,

:five, and fifteenpins, respectively, upon .one reciprocation, i.e.anadvancing motionfollowed by a retracting motion ,to-starting position. The solenoids action-to advancethe rods and vpresser heads is momentary, and the spring .25 .acts to retract said rods and .headsto normal position.

Ihe horizontalshaift '8' is connected to amechanismof the vending .smachine which .controls :the dispensing operation, and which operation takes place :only after a part-circleprotation of said shaft 8 of an .arcuate-extent,atleast equal to-'the'arcuate extent of the-totalpresser-head assembly it.

With the described accumulator such partcircle-rotationiof the shaft -5, to cause .a dispensing operation of themachineresults from the 'deposit, in the cointboxes, of-,a twenty-five cent piece in the box 38,0112. deposit in theboxes .36 and 3? of a combinationof-fivecent or ten cent coins totaling-twentyefive cents.

The'mechanicalaction is as follows: If a twentyefive cent piece is deposited ,in the coinboxtdthe solenoid-32 operates tocause one reciprocation of the pushrod-ZZ. Upon reciprocation of the push rod 22, the presser-head 13 will likewise reciprocate, as will .the remaining presser heads ll, lB,-and.l5,,by reasonof the cooperating stop assembly previously described.

-;When this occurs twenty-five. of the pins, lit-are advanced outwardly through the .control disc 9, and clear ,of the. stop,39 whereby the lmotoifl H then rotates the control disc 9 through a part circle whose extent is suflicient to cause the vending machine to operate. The twenty-sixth pin then abuts the stop 39 (as the next lead pin) to prevent further immediate rotation of the disc.

-he motor I l is placed in operation at the outset of a deposit of a coin in one of the coin boxes by anteans of a circuit (not shown), and thereafter'is maintained in operation by said circuit until the dispensing operation is complete, when the motor M is stopped. The motor belt slips pulley 52 except during said part-circle rotation of the disc.

If :a coinbinationof two ten-cent coins and a five-cent coin are placed in the boxes 36 and 37, respectively, to total the required twenty-five cents, the described solenoid and push rod assembly will cause the presser heads ll, l6, and IE to reciprocate twice, shifting two successive banks of ten pins to advanced position, and the presser heads it and i5 will be reciprocatedonce to advance a bank otfive pins to complete the twentywfive total.

Similarly, five five-cent pieces .placedin the coin box 36 would cause the presserheads =16 and 15 .to be reciprocated five times, eachtime advancing five pins .to total the required twenty- The device .is therefore operative to accumulate .the total value of the coins deposited inthe coin boxes, regardless of thenumber or combination of said coins required to make up the predeterminedtotal value.

,In those instances where, ,for example, a .onecentsales tax is required, the part-circle rotationrequired of the shaft .8 .to cause actuation of the dispensing mechanism is the total .arcuate extent .of twenty-five pins, or other .pre-selected number, plus one. It is thereforenecessary,to insert one .cent in .the .coin box 3.5 in. additionto the remaining coins required .tototal the sales price before the dispensing machine will operate; the accumulatingprocess being ,thesame as hereinbeforedescribed.

Below the stop .35 the advanced pins ride. onto an arcuate care to concentric .to the shaft .8, which camextends from ad-jacentsaid stop 39 about the lowerportion oftherow of pins and up to the adjacent .end of the presser head [8. Thus, by the time the pins travel about the bottom portion of the row and up tosaid presser head it, the arcuate cam 49 hascallsedretractiorrof.v the pins to theirnnormal orstarting positionin the upper portionof the row, ,as infiigj.

To prevent the pins retracting beyondthevertical plane of the outer face of the presser head assembly, there is an arcuate limit .plate mounted concentric to .the horizontal shaft .in

predetermined position inwardly of the control 'coin boxes.

From the foregoing description it will be readily seen that there hasbeen produced such a device as substantially fulfills the objects ofthe invention, as set forth herein.

While this specification sets forth in detailjthe present and preferredconstruction of the device, still in practice such deviations ,fromjsuch parture from the spirit of the invention, as defined by the appended claims.
